Q, fir 'd i5 Patented Oct. 20, 1931 UNITED snares PATENT OFFICE RAYMOND T. CLOUD, OF CHICAGO, ILLINOIS, ASSIGNOR TO ORCHESTRAPHONE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE Hex-cram) CARRIER THEREFOR Application filed- July 16, 1928. Serial No. 293,098. Renewed August 14, 1931.

This invention pertains to apparatus for reproducing sound waves such for example as music, and moreparticularly to a pick-up supported by a tone arm and carrier therefor adapted for use in connection with the electrical reproduction of music from phonograph records and the like.

An object of my invention is the provision of a pick-up arm carrier of simple and inexpensive construction and adapted to be associated with the arm without in any way interfering with the operation of the pick-up during the time that it is in cooperation with the record being reproduced.

Another object of the invention resides in the provision of a pick-up arm carrier including electromagnetic means for holding the pick-up on the-tonearm out of coopera tion with the record.

In accordance with the general features of my invention I provide a carrier for atone arm mounted on a common axis with the tone arm and including electromagnetic means for I holding the reproducer on the end of the tone arm outof cooperation with the record.

Another feature of my invention resides in the provision of a common mounting for the tone arm and carrier which permits of the carrier being moved away from the tone arm after the tone arm has been lowered into cooperation with the record.

Still another feature of this invention has to do with the provision of a carrier having adjustable means for engaging the reproducer on a tone arm designed to hold the reproducer on the tone arm at various distances from the record.

A further feature of the invention relates to the provision of a common mounting for a tone arm and carrier which mounting includes stops for limiting the movement'of the carrier as well as of the tone arm.

Other objects and advantages of my invention will more fully appear from the followinc detailed description taken in connection with the accompanying drawings which illustrate a single embodiment thereof and in which Figure 1'is a plan view of a tone arm and in place by washers 20, 21, and a bolt 22 10c carrier therefor embodying the features of my invention;

In the drawings:

Like reference characters designate similar parts throughout the several views. The reference character designates tone armhaving one end 16 bi urcated, as lllustrated in Figure 4, so as to accommodate one end of a tone arm extension 17. This end ofthe extension 17 has secured to it a pin 18, the ends of which are journaled in anti-frictlonal elements 19 carried by the legs of the bifurcated end 16 of the tone arm proper. Each of the anti-frictional'elements 19 is held igenerally a threaded into the corresponding end of the pin 18.

The other end of the tone arm extension 17 carries a reproducer designated generally by the reference character 25, which in the present' instance comprises an electrical pickup for reproducing the sound waves on a record 26 which may be of the phonograph type disposed on a phono aph turntable 27. The turntable 27 may i e operated continuously by any suitable mechanism such, for example, as a conventional electric motor (not shown).

The reproducer 25 comprises an enlarged housing 28in which is disposed the electrical pickup mechanism designated generally by the reference character 29 in Figure 4. This pickup mechanism may be 'of the same character as that disclosed in my copendin patent application Serial No. 234,447 filed llovemher 19th, 1927. This pickup mechanism 29 is 'operatively connected to aneedle holder 30 adapted to receive a needle 31. for cooperation with a record 26. The waves recorded in the electrical pickup 29 are transmitted through ithe tubular extension 17 and the tubular tone arm 15 to a suitable amplifier (not shown). Also the housing 28 has connected to it an extension 34 including a spherical portion 35 arranged for cooperation with the holding means in the carrier which will be more .fully described hereinafter.

. From the illustrations of the tone arm in Figures 1 and4 it will be evident that the tone arm extension 17 including the reproducer 25 can be pivoted upwardly over the top Also it will be noted that the tone arm 15 includes a mounting portion 36 including a central bore 37 (Figures 3 and 4) in which is tightly fitted one end of a tubular element 38. This element 38 is journaled in spaced antifrictional elements 39 and 40 which will be more fully described hereinafter in connection with the mounting for the tone arm and carrier. I shall now proceed with the description of my novel carrier for the tone arm.

The tone arm carrier is designated generally by the reference character and includes an extension 46 rotatably mounted upon a fixed mounting tube 48 which will be more 1 fully described hereinafter. j The carrier 45 includes a hollow housing 49 out of which extends the free end of a pivotally mounted member 50. Thefree end of this member 50, as shown in Figure 9,has a threaded opening 51 into which is threaded one end of a stud 52 having its upper end formed into an enlarged portion 53 defining an arcuate seat 54 designed to accommodate and-receive the spherical portion 35 onthe extension 34 of i the reproducer25. It will be evident that the stud 52 is adjustable to various positions whereby it can hold the pickup arm at various distances from the record 26 (Figure 2). After the stud 52 has been adjusted to the desired position it may be held in that position by the setscrew 55 threaded into the free end of the pivotally mounted lever member 50. The other end of the member 50 is pivotally mounted upon a pin 56 secured to the side walls of the carrier housing 49.

The underside of the carrier rod 50 has formed integral with it a slanting or tapered surface comprising a cam 57 (Flgure 5) cooperable with rollers 58 rotatably carried y the squared portion 59 of a plunger rod 60. Each of the rollers 58 (Figure'7) includes a reduced portion 61 arranged for engagement with the cam portion 57. It will be noted that'the cam portion 57 is of a slightly less thickness than that of the member 50 proper, so that this cam portion extends between the inner edges of the rollers 58.

One end of the rod extends through an apertured lateral extension 64 formed inte gral with the base plate 65 of the carrier. The portion of the rod 60 between the rollers andsthe extension 64, as shown in Figure 5, is

enlarged-and formed into a squared portion designated generally by the reference charac-.

of the tone arm 15 p p in much the same ithe rod 68 extends through the bifurcated manner as the reproducer on a phonograph isv pivoted to a. position above the tone arm.

ton 70 is formed tubular so as to accommodate one end of a compression spring 76, the other end of the spring abutting the'closure plug 75. This spring is at all times adapted to urge the piston in a direction away from the closure plug 75.

lhe base plate 65 of the carrier housing 49 is secured to the cylinder block 74 which is in turn secured to a frame plate 77. This frame plate is right angular in construction, one leg of which extends in front of the mechanism shown in Figure 3, but is not illustrated in the drawings for sake of clearness, and the other leg of which being shown in Figure 3 asservingfor a support for the electromagnetic coil 78. It is, of course, to be noted that the frame member 77 as wellas the coil 78 are disposedwithinzthe carrier The coil 78 is positioned in a horizontal plane and has one of its ends rigidly secured to the vertical leg of a metallic angular member 79. The vertical leg of the angular member 79 is rigidly fastened to the leg of the plate '77 shown in Figure 3. Also the top suuface of the horizontal leg of this angular member 79 abuts a lug 80 formed integral with and extending inwardly from the carrier housing 49. Bolts 81 serve to fasten this horizontal leg of the angular iron member 79 to thelug 80 so as to rigidly hold the coil in place within the carrier housing 49.

Associated with the free end of the electromagnetic coil 78 is a right angular armature 82, one leg of which is disposed adjacent the core of the coil and the other or horizontal leg of which extends over the horizontal leg of the angular member 79. This angular member 82 is pivotally connected to the edge of the horizontal leg of member 79 by a stud 83 extending through a slot formed in the member 82 at its vertex.

The horizontal leg of the angular 'armature 82 has secured to it a U-shaped element 85, the legs of which straddle the electromagnetic coil 7 8 and have their lower ends associated with the plunger rod 60. In Figure 3 it will be noted that the lower ends of the legs of this element 85 are connected by a pin 86 upon which is mounted a rotatable roller 87. This roller is designedto engage aligned notches 88 (Figure 5) formed in the bifurcated end 71 of the plunger rod 60. The purpose of the roller 87 is to cooperate with the U-shaped element 85 and the armature 82 in holding the plunger rod 60 and the piston in the positions shown in Figure 3 so that the member or arm 50 will be maintained in its uppermost position. In other words, the energization of the coil 78 attracts the vertical leg of the armature 82 causing the U-shaped' element 85 to be moved upwardly, whereby the roller will engage in the aligned grooves 88 of plunger rod 60 when the plunger rod -60 is moved into its retracted position within the carrier housing In the assembly of the carrier 45, the elec tromagnetic coil and the associated plunger rod mechanism is mounted as a unit within the carrier housing 49 and suitably anchor ed therein. The housing 49 has threaded init an adjusting screw 90, the end of the shank of which is adapted to engage the top surface of the member or arm 50 and to thus serve as a stop to limit the upward travel of this member 50. I

I shall now proceed to describe in detail the novel. mounting for the carrier and the tone arm which I have previously referred to in a general way. The fixed tubular member 48 upon which the carrier 45 is pivotally' mounted extends through an opening formed in the supporting board 91 '(Figure 3).

for holding the carrier and tone arm in place" on the supporting board 91. Threaded into the member 92 is a setscrew 94, the inner end of which is adapted to extend into an annular groove 95 formed in the periphery of the tube 48 for the purpose of anchoring the tube 48 against rotation.

As shown in Figures 1 and 10, the annular flange 93 has a portion cut away as indicated at 96 so as not to interfere with a tube of insulation 97 secured to the housing 49 of the carrier. The conductors 98 for the electro magnetic coil 78 are threaded through this tube 97 as will be evident from Figure 2.

Also in Figure 1 it will be evident that the extension 46 of the carrier includes an annular flange 99 disposed adjacent the top surface of the flange 93 of tube 92. A portion of this flange is cut away as indicated at 100 so as to accommodate the stop screw 01' pin 101 secured to flange 93. This pin 101 is designed to cooperate with the shoulders formed by the cut out portion 100 so as to limit the movement of the carrier 45 about the axis of the fixed tube .48.

In Figure 3 it will be noted that the mounting portion 36 of the tone arm abuts the top of the extension 46 of the carrier and is rotatably mounted upon the top edge of the fixed tube 48. The extension of the mounting portion 36 comprising the tubular ele-.

ment 38, as previously pointed out, is journaled in the spaced ball bearings or anti-frictis-nal elements 39 and 40 mounted within the interior of the fixed tube 48. The lower end of the tubular element 38 has mounted on it a collar 104 secured thereto by asetscrew 105 (Figure 10).

'Attention is directed to the fact that the lower end of the fixed tube 48 is formed into a hexagonal shape so as to facilitate the unthreading of the tube from the tubular element 92 when the parts are being dissembled. The collar 104, as shown in Figure 10, is'disposed within this hexagonal portion which is designated by the reference character '106. A portion of the hexagonal end of the fixed tube 48 is cut away'so as to provide-a slot 107 for .accommodating the head of stop screw 108 secured to collar 104; The shoul-,

tightly fitted in the mounting portion 3 of the tone arm, it necessarily follows that by rimiting the movement of this tubular ele- .ment the movement of the tone arm about the axis of-the fixed tube 48 will also be limited. Incidentally, it will be noted that the wires 32 for the electrical pickup 29 are threaded through the bore of the tubular element 38 as shown in Figure 3.

The operation of the above described mechanism is briefly as follows: To effect raising of the needle 31 out of cooperation with the record 26, the plunger rod is moved inwardly into the carrier housing 49, thus causing piston to compress the spring 76. During movement of the piston into the cylindrical bore 73 of the piston block 74, air is forced from the bore and escapes out of the block around the periphery of the piston 7 0. Moreover, upon the grooves 72 in the end 71 of the plunger rod 60 reaching a position 0 posite the roller 87, the energized coil 8.

immediately acts upon the pivotally mounted armature 82 to draw the U-shaped element 85 upwardly so as to cause the roller 87 to be wedged in the grooves 72 thus resulting in the plunger rod 60 being locked in the position shown'in Figure 3.

It will, of course, be evident from Figure 5 that during the above discussed movement of the plunger rod 60 the rollers 58 engage the slanting 'or cam portion 57 thereby gradually moving the pivoted member 50 to its uppermost position shown in Figure 3. Thereafter, if the spherical portion 35 of the pickup housing 28 be placed on the curved surface 54 of the head 53 of stud'52, the needle 31 will be clear of and above the plane of the record 26 on turntable 27.

When it is desired to lower the pickup 25 into cooperation with the record 26, the same may be efiected by de-energizing the electromagnetic coil 78 which results in the U-shaped element 85 gravitating to its lowermost positionwhereby the roller 87 is moved out of cooperation with the grooves 72 in the end 71 of the plunger rod 60. This allows the compressed spring 76 in the piston 70 to become active to urge the piston outwardly and'away from the closure plug 75. The

movement of the piston in a direction away from the plug, however, is retarded due to the fact that the aiLpressure on the outer side of the piston is greater than that prevailing in the interior of the piston and in.

the cylindrical bore 73. That is to say, as the pistonis forced in a direction away from the plug by the spring, the air gradually leaks into the interior of the cylinder around the periphery of the piston so as to equalize the air pressure on both ends of the piston. This equalization of pressures is gradual so that the piston 70 is in effect cushioned by air as it is moved under the efi'ect of the sprin 44. I

This gradual movement of the piston by the spring results in the lowering of the piv oted member 50 whereby the pickup needle 31 is slowlylowered into cooperation with the groove of the record 26. In other words,

Leeawo rier 45, both the carrier and the pickup may be swung about the axis of tube 48 to a posi tion in which it is desired to lower the pickup so as to cause its needle 31 to engage the record. Thereafter, the de-energization of the electromagnetic coil results in the gradual lowering of the needle into engagement with the record as previously described. When the pickup is in cooperation with the record, the carrier 45 (Figure 1) can be swung in a clockwise direction clear of the tone arm and pickup.

It is also to be noted that the pivotal movement of the tone arm 15 and its pickup 25 is limited by the head of screw 108 engaging the abutments or shoulders defined by the cut out portion' 107 in the lower or hexagonal end 106 of tube 48 (Figure 10). The

ivotal movement of the carrier 45 is limited y the head of screw 101 engaging the shoulders or abutments of the flange 99 connected to the extension 46 of the carrier.

Now, of course, it is to be understood that although I have illustrated and described in detail the preferred form of my invention, the invention is not to be thus limited, but only in so far as defined by the scope and spirit of the appended claims.
